Okay, so I've been testing my streams and it seems as though I can get Input audio to work perfectly; I can hear everything that is picked up by my mic. From what I understand, procaster is supposed to be able to stream the audio directly from the output source, correct? For some reason, It doesn't seem to work. The two options in the audio settings tab under preferences are "Default input device" and "Realtek HD audio input"... I think I've read somewhere that you are also supposed to have a "speaker output" option or something along those lines. I have nothing like that. I should note that my "speakers" are a pair of headphones plugged into the back of my pc. I don't know if this makes a difference.
